Patients with infarctions in the territory of the right middle cerebral artery (RMCA) sometimes present with an agitated confusional state. We reviewed clinical data on 46 patients with RMCA infarcts and compared neurologic findings in patients with and without agitated confusion. Neither of the two patients presenting with agitated confusion showed obvious localizing neurologic signs; subtle m...

Rapid and accurate detection of glaucomatous damage at its onset or on its progression is desirable for optimum patient management. Tonometry alone is insufficient in ensuring adequacy of therapy; also required are stereoscopic optic disc review and quantitative perimetry. Signs of early optic nerve head damage from primary open angle glaucoma (POAG) include nerve fibre layer haemorrhage, a gen...

We asked 12 right-brain-damaged patients (6 with left neglect signs and 6 without left neglect signs) to perform a straight ahead pointing task and a visual detection task with lateralized motor response, in order to investigate the relationship between the position of the egocentric reference and response time and accuracy in producing lateralized arm movements. Results showed that there was n...

Drug recognition and examination programs are widely used to detect drug impairment in motor vehicle operators. Visual tests a key assessment the detection of cannabis-related impairment. Participants were recruited via social media from medical cannabis community Southwestern Ontario, Canada. Twenty-two participants completed full observational trial design.

Purpose. To present a unique case of Non-Hodgkin's-Lymphoma- (NHL) associated compressive optic neuropathy. Method. An 89-year-old male presenting with acute unilateral visual loss and headache. Results. Patient was initially diagnosed with occult giant cell arteritis; however after visual acuity deteriorated despite normal inflammatory markers, an urgent MRI scan revealed an extensive paranasa...

Extension of sphenoethmoiditis into the orbital apex may result in visual loss and ophthalmoplegia, but minimal signs of orbital pathology such as proptosis, chemosis, or lid edema. This entity is termed orbital apex syndrome. The case of a 74-year-old woman with orbital apex syndrome and irreversible unilateral visual loss secondary to bacterial sphenoethmoiditis is presented. This case, and o...
